SAML configuration for HANA cluster

Hi,

We have a client which connects with HANA server using SAML authentication.

In the client we generate Base 64 certificate with HANA hostname  as a parameter.

Now our concerns in case of HANA cluster machine , are as follows:

A.  Do we have to configure SSL separately on all the HANA Boxes(I.e Master,worker, standby) or not

B.  When we generate SAML certificate from client side, we have to provide HANA hostname as a parameter. So, in case of clustered HANA  setup, how to generate certificate from client which can support HANA failover scenarios. (Which hostname do we have to provide in client side for certificate generation)

Thanks for the help.

Regards
